Be it=known thatrlVJA-MnsfNoBnn EDNVA a subject` ofthe. King; of Great Britain', re-,.

si din gat South Kensington, London, .Enga .v land have. invented certaink `new. andaiseful Improvements in or Relatinggto .Motor-Car. Itadiators,A of fwhich thefollowing; is :a speoification.

The obj ect of ,this invention is: to.` prevent the cooling,waterI oan Aautomobile: engine. from.. getting above a .f certain .temperature .i

and to prevent ,radiators from,,bursting .ow-,-T

stoppage in ithepipesr due Lto solderA or Vfotli'er foreign matter. Thefdevicecomprisesan attachment l adapted :to ,be securedy to. the .ra-A dirator at: thel water'. illinghole ,in place..` ofE the ordinary;A radiator r-cap, .and .such-fattacln phere. Gauze may be fitted acrosstthecfront,

or rear cowl fopening for .both and. the bot# tom of the vertical pipes, which latter..w.ill

usually be just clear of the water in the' radiator.y The @rear Walla A.of the intake portion of the cowl slopes forwardly and upwardly from the vertical pipe, hereinafter referred to, reaching nearly to the inlet end of the cowl and forming a partition to cause the current of air to flow from the forward end of the cowl down to the radiator water, and I provide'a pipe leading from the rear portion of the'cowl down to or into the radiator to cause water condensed in the rear portion of the cowl to flow back into the radiator.

I provide a throttle or like means for controlling the current of air, which may be in the form of a valve common to an aperture in the partition of the pipe and to the two passageways formed in the pipe by said partition. The rear cowl opening may be of any suitable shape and I may provide any other means for preventing condensed moisture from dripping or blowing oil' the attachment.

My invention will be more clearly understood from the'following description aided by? thetannexed'. .dra-wings which; shoiw al si-I'nple construction. of .mydevice, in which!V Rignrefl z is -,aevertical section. .l3` ig fure.. 2. ,i s a :side elevation.- .y According to: the construction.- illustrated, I iprovi de a, tube/A and ion. this' .tube A. ,If mount Ia cowl B; and.centrallywithin they tube. .I v'position partition IC., whichihas iits e upper end extending in an angulardire'ctioii across .thecowl :and its lower end"l extend! ing preferablypljtust belen7 Vth'elflcf)werfenc'il of the tube A, lthe -.tube andflcowl beingfthereby divided.intoitwotcompartments.. l 4

I may form an aperture in the partition C and pivot to the tube a valve M which preferably is of butteriyl forni and lits the aperture in the wall C so as to leave two clear passages on either side of the wall C, and I connect to the spindle N of the Valve, which is journaled in bearings formed in the tube A, a handle P positioned outside the tube A and working within a quadrant race Q so that, by operating the handle, the valve may be positioned to leave ay clear passageway on both sides of the partition to and from the radiator or be actuated to completely shut off or throttle both passagewaysl from the radiator.

I also form a second partition R .in the cowl to the rear of the partition C to conduct the hot rising vapours to the upper portion of the cowl and so bythe vapours coming in close proximity to the cold iutube A and through the partition C, whereby all water of condensation will pass back into the radiator and, if desired, s uch pipe S may be provided with an extension S1 to take the water of condensation directly into the water of the radiator and so obvlate any splashing.

By such a device the cold air flowing linto the mouth D of the cowl and passing down the tube A into the radiator during the travel of a vehicle to which it is affixed will act upon and cool the water inthe radiator and the amount of the steam issuing from the opening at the portion E will indicate to the driver whether the water is being kept cool enough.

What I do claim as my invention and desire to secure by Letters Patent is l. A device of the character described comprising a pipe of which the lower end is adapted for connection to an automobile radiator, a cowl kconnected to the upper enll of said pipe and in communication therewith, said cowl having an inlet at its forward end and an outlet at its rear end, a partition extend-ing transversely of said cowl rearwardly and downwardly from the forward end of the cowl into said pipe and dividing said pipe into an'inlet passage and an outlet passage, and a second partition extending partially transversely of the cowl at a point rearwardly of the upper end of said pipe.

2. A device of the character described comprising a pipe having its lower end adapted for connection with an automobile radiator, a substantially bell-shaped cowl connected tothe upperrend of said pipel and in communication with the latter, said cowl having its mouth adapted to face torwardly of the vehicle to which the device is attached and having an outlet at its rear end, a partition inv said pipe dividing the pipe into an inlet passage and an outlet passage and extending upwardly beyond the upper end of the pipe transversely of said cowl, a second partition in said cowl extending partially transversely of the latter rearwardly of said irst-nained partition, and a conduit extending through said pipe having its upper end connected to said cowl at a point rearwardly of said second partition and its lower end projecting beyond the lower end of said pipe.

3. AV device for attachment to the radiator of a motor vehicle', comprising a pipe having a longitudinally extending partition therein forming a pair of passages, said par tition having an aperture, a cowl connected to theupper end otsaid pipe andopen to the atmosphere at both of its ends, said cowl having a partition forming a continuation of the partition in the pipe, and a valve in said pipe adapted toswing into position to close the aperture in said partition and also into position to closethe passages in the pipe.

4. A device for attachment to the radiator of a motor vehicle, comprising a cowl adapted to 'face `forwardly on the vehicle and having forwardly and rearwardly directed apertures, a partition in said device formingA passages communicating` with the radiator, said partition having an aperture, and a valve common to said aperture and to said passages.

ln testimony whereol have hereunto set my hand.
